As recommended by my Year 11 GCSE Physics students – myGCSEscience.com is an excellent site that has video clips on all areas of GCSE science, sorted into modules for the AQA Core Science (B1 C1 P1), Additional Science (B2 C2 P2) and Separate Sciences (B3 C3 P3).

Here is an example from P3 on Convex Lenses

Each video comes with a pdf you can print, with pictures of the slides and spaces for your own notes – so you can build up your own revision guide.

Plus – since all videos are hosted by YouTube – you can use your mobile or tablet to watch them.

The Big Bang made hydrogen – but where did the other 91 natural chemical elements come from? These clips from the BBC’s Wonders of the Universe by Brian Cox answer the questions…

How do we know there are only 92 elements – even out in deep space?

All atoms give out only certain colours – a spectrum – based on how their electrons behave. They also absorb only those colours too. You might have seen this by doing flame tests or looking at gas discharge tubes using a spectroscope.

How did all these elements get made?

Every element in nature was made in stars, during their “life and death” by a process of nuclear fusion which gives out energy up to Iron (so these are made as stars live and die) but needs energy for heavier elements (which means these are made when a star explodes)

Oil – the fuel everything we do runs on – hit peak production in 2006 they think. This means with an every increasing popluation (most of whom at the moment don’t use oil anywhere near as much as we do in Europe/America) the amount of oil to go around will stay the same, or even start to drop, sending prices upwards.

In this chart we can see what they expect over the next 25 years. The darkest blue is the oil we are currently pumping – that’s on a downwards trend.

Above that is oil we know about, but are not pumping yet – also on a downwards trend. To stay level we have to hope we find new reserves – oil we don’t even know about yet.

To top up the levels we need more Liquified Natural Gas and BioOil (oil from plants).

Yep, another post on bang. this week we see why at the moment, planes cannot fly due to the volcanic ash, why it is so easy to ski, even though snow isn’t slippery and how can we reduce CO2 emissions when we are burning coal.

You may have also seen adverts about training your brain, which is all on the bang website (the link is below along with the bbc iplayer link) . The website also shows you what happens to a candle in zero G and how to turn water into ice with a single bang. You can also ask Dr Yan any unsolved questions you have got, like whats deja vu, why do onions make you cry and what is the meaning of life (although he may not be able to answer the last one, best person to ask is Matthew Bellamy :D). I am also pretty sure the 3D Doctor. Who is still there, with his new assistant called Amelia! 😀

Matt, explaining the Meaning of Life

Bang website, and i have just looked for the new bang episode on iplayer and it’s not there not sure why so I’ll keep looking 😀

Yep, another Band Goes the Theory Blog for the new episode (there wasn’t one last week as i was on holiday). This week Jem makes steel from iron and another unusual (smelly) ingredient, Dallas shows us he can’t swim and tries to improve by looking at another mammals techniques, Liz finds out if we could live forever by looking at Naked Mole Rats (not the ones off fallout 3) and Dr Yan asks us, what is similar between fizzy drinks and diesel. So heres the link to the Bang website and a link to bbc iplayer where you can catch up if you missed any episodes.
